when a couple similar lights popped up on DX I thought it over :) I think it could work really well but it is low on my list of projects (but mostly just because so many other projects already have time and money invested).
Viffer, actually that particular MF 35W is a well known under-performer. :) Measured many times to be in the 50k cd region. Check out tatjamagic's comments in CPF section (and my dialoug with him).
But yes, the 20/24W HIDs are actually even more inefficient. You'd want to go high power with those flashlight host type of HIDs. But don't mix up with those 35W automotive ballasts, those are really different animals....esp after putting them into the big hosts. The Microfire 35W has OP, the SMO ebay/aliexpress 35W gets you slightly over 100k cd actually.
His XTAR S1 figures seem a little low, but anyway that really puts to rest my doubts and i hope the others too!
WOW!
Where do i sign up for it man? :D I mean the flashlight looks cool looking anyway.
Seems to be in the 5000 lumens OTF region.
Throw is a mix. The microfire 35W is measured by many members to be in the 50-55k cd range. Its getting quite high here, and the S1 + SR92 are quite low.
But anyway one thing i can't make sense of is that in the first photo it clearly shows the throw of the 2D80 9 XML to be lower than the SR92. (1) operator error in that first photo maybe?
Still some questions unanswered. Yeah provocative measurements....plus pictures. LOL!
Interesting! And provocative! Just occurred to me that it migth not be a good idea to measure even at 3 metres, which they seem to be doing due to the small spot size.
This would be more indicative of throw. Many metres away.
Haha, so I was just telling about the brand not the model then, How many languages do you actually speak 2100?
I only know spanish and a not that good english :(
I think it was called MS2010 the one with the aspheric lens.
Meh. They probably run each emitter at 1 amp. It seems like a huge waste of money. 3x XM-Ls at 3 amps already produces a good 36 or so watts of power. That is already pretty difficult to heat sink.
Plus, the XM-L curve of wattage to lumen output is pretty linear up thru 3 amps too. So doing 5 XM-Ls at 2 amps isn't really THAT much better than 3 XM-Ls at 3 amps each from an efficiency standpoint.
Putting 9 of them in a light, especially right next to each other seems like a terrible, awful idea.
Don’t xpg put out about the same amount of light as xml up to about 1.5A? Why didn’t anyone ever do anything like this with them? A few less lumens for a lot more throw. Or 9 1a xre. It seems the multi-emitter single-reflector would throw much better than the multiple small reflector setups.
cool monster for the positions of the LEDs I'm wondering if it don't use a Peltier's cell but probably not, wouldn't be efficient
In every multi-LED app that I've seen in a single reflector, throw is compromised.
I have made (or purchased) several in varying sizes, all the way down to twin XPGs in a single P60 reflector ("Linger Special")
Due to packaging, none of the LEDs are optimally positioned in the reflector. This is seen in the relative lack of collimation compared to the S1.
Hi Joe,
It seems that they are driving each at about 1.8A thereabouts, to do 5000L out-the-front (calculated using the excel LED output calculator that you can find here on BLF). That's from my calculated guess on the ceiling bounce on the lux meter.
Also look at the temperature rise, even with the high mass of 1kg for the light/fins, we are doing a delta of 31 deg C or 16 deg C rise to 47 deg C for a run of 10 minutes. XTAR S1 is 18 deg C delta and SR92 is 19 deg C. I have seen the Xtar S1 in detail, no way that it or the SR92 has a lousy thermal path from the MCPCB to 6061 host.
You mentioned 2A vs 3A. For info : 1.8A = 658 lumens @ emitter (cold), and 3A = 937 @ emitter (cold). 5 LEDs x 1.8A = 9A = 3290L emitter and 3 LEDs x 3A = 9A = 2811L emitter. That's a 17% difference. I guess it's not a lot but that's not insignificant as well. Esp if you are pushing the envelope....
I just want it to be cheaper.... 
Haha...nah i just know 3 languages. English, Chinese and the Cantonese dialect. I know a bit of Hokkien, that's all.
Yes, the range is MS2010...they have several hosts like 2D60 and 2D80 (probably denotes the head diameter).
HKequipment.net used to carry flydragon but they stopped. Here's another one : http://www.ebay.com.sg/itm/Flydragon-Fei-Long-MS2010-SST-90-SST90-LED-Flashlight-/110830649774?pt=LH_DefaultDomain_0&hash=item19ce0581ae
If you ask me, it's too expensive though. Check out the GB in shoudian for the China folks, it's not very expensive.
I guess if anyone is really interested they can ask HKE. HK is a good place to start, they are so near to Shenzhen. It's like our country here crossing over to Malaysia's....just over a bridge. City centre to City centre is just like 30km.
That's a good idea. If we swap out the 5 x XM-L in the TR-J12 to 5 x XP-G i'd estimate that as maybe 35k cd range and calculated @ 1.5A you'd get 2000 lumens OTF, just a slight drop in lumens. TR-J12 is 24k cd.
There is a 3 x XP-G budgetlight, you can see it in ebay, but it's not very popular. The reason is probably just that, XP-G does not sound impressive for the general folks/beginner flashaholics.
I kind of agree w/ you bobk - I mean, when you walk outside in daylight, you're not shocked...so how shocking can a flashlight be.
on the other hand, maybe you could try taking your big 'guns' back out and standing down range from 1, then down range from both and the difference would be more noticeable ;)
now it's available at intl-outdoor.com, the price is ridiculously high
Most of you probably would not be able to see the characters unless you have chinese support, but they had an offer for the first 10 guys in each 4/5/7/9 XM-L category, think it's a special price and free battery. The next 10 guys would be special price but no free battery. After than full price and no free battery.
http://www.shoudian.com/thread-235304-1-1.html
They have U2 and T6 3C options.
9V protection and 6.2V protection for 3D and 2D respectively.
Anyway I'll just post there webby here. http://www.feilong.us/
For more pictures, pls go to shoudian and see post 2 by Feilong. I am posting just 1 pic here from my gallery as I think they don't want people to hotlink direct from their site. (bandwidth probably)
My parents will be in Shenzhen/Zhuhai/Guangdong next week but I don't think it is cheap over there even with the help of my relatives. LOL!
For me i'll be in Beijing the week after next....but i think nothing much to buy as far as flashlights/lxxxx are concerned.
lol. You would not see me having 9 18650 batteries in that light! And some people are afraid of 2-4 18650s in one light.
Since it at has 15A max current. That would be 1,67A to each led. So theoretically it should be about 600 lumen on each led. 600*9:5400 lumens.
Probably a nice light if you want 5000 lumens from three 32650 batteries paired with long lasting LEDs. Very expensive tough.. Way too expensive! Altough it is probably the sickest XM-L lights out there! So with no opponents it kinda can justify its price.. Only people with way too much money will buy it tough. Lucky ba... ;)
btw.. would it not be better to just buy a 55/65w HID if looking for a 5000+ lumen light in that price range?
(no clue about HIDs, or what price range decent lights are.)
Probably it has low 5000 lumens OTF. My 65 watters gets me approx 3800-4000L OTF. (difficult to measure because there is an optimised burn position which is not vertical, so a ceiling bounce gives you a reading that slides down). The 85W might not even touch 5000 lumens OTF....still plenty bright though.
Don't bother with the wattage though. Measurements are better. One thing is that it's extremely difficult to get a current reading for those aluminum flashlight host HIDs that you see on Ebay/Aliexpress.
A 100W ballast @ 24V input with 100W bulb (just for measurement's sake, coz 24V it has higher efficiency) can net you about low 7000 lumens OTF on a 6" reflector with the thick glass lens intact (cuts about 11%).
To look at this from a more different perspective, I have a total of about 37000 lumens OTF from the HIDs. 
(conservatively speaking, > 30000 lumens OTF, confirmed).

Be fun to review something that outrageous. I guess they got any heat issues sorted, right? I can turn this thing on high without losing an arm?
Damn . . . . nine XM-Ls.
wowFoy
The "problem" I see is the throw is not apparently huge for that power consumption, and I feel a big part of it is not usable for flood either, with much less lumen output you get a more than usable light dimmer but enough.
I would like to see a light with 3-5 XM-L with deep and not very big in diameter, it might be a better compromise between flood and throw (at least in my head).
Exactly what I was thinking as I was reading this. I like bright torches, but this is getting into the league of having to wear a welding helmet so you can use it and not damage your eyes!
“I wear my sunglasses at night, so I can, so I can,” turn on my torch without going blind!
Awesome lights though
